Assembly, structure and magnetic property of one cyano- and oxamidato-bridged mixed valence CuI/CuII complex

One new cyano- and oxamidato-bridged mixed valence CuI/CuII complex 1 [image] (oxdipn is the dianion of N,N′-bis(dipropylenetriamine) oxamide) has been synthesized and structurally determined. Complex 1 consists of a one-dimensional zigzag chain –CuI(CN)–CN–CuII-(oxdipn)-CuII–NC–CuI– with CuII and CuI atoms linked together by oxdipn ligand and cyanide. Magnetic calculation on complex 1 showed that the oxamidato bridge transmits antiferromagnetic interactions between the Cu(II) ions.
